Method of indicating uplink feedback information and method of transmitting uplink feedback information

ABSTRACT

A method of indicating uplink feedback information includes: dividing time/frequency resources into at least one time/frequency resource set for uplink control information; notifying user equipment (UE) a division rule and/or result with respect to the time/frequency resource set with respect to the time/frequency resource; counting, based on the set to which time/frequency resources for transmitting uplink feedback information corresponding to downlink data for the UE belong, pieces of the uplink feedback information in a preset manner; and transmitting current count values to the UE. As such, it can be ensured that the number of pieces of uplink feedback information to be transmitted from the UE by multiplexing time/frequency resources for transmitting uplink data is the same as the number of pieces of downlink data transmitted from a base station and corresponds to the uplink feedback information, thereby ensuring good communication between the UE and the base station.

CROSS-REFERENCE TO RELATED APPLICATION

The present application is a national stage of International ApplicationNo. PCT/CN2017/113386 filed on Nov. 28, 2017, the disclosure of which ishereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of communicationstechnologies, and in particular, to a method of indicating uplinkfeedback information, an apparatus for indicating uplink feedbackinformation, a method of transmitting uplink feedback information, anapparatus for transmitting uplink feedback information, an electronicdevice, and a computer-readable storage medium.

BACKGROUND

During interaction between user equipment and a base station, if uplinkdata and uplink control information transmitted by the user equipmentoverlap with each other in a time domain, the user equipment canmultiplex a time/frequency resource for transmitting uplink data andtransmit an uplink control signal on the time/frequency resource fortransmitting uplink data, that is, uplink control information (UCI)piggyback. When the uplink control signal is transmitted on thetime/frequency resource for transmitting uplink data, there may be aproblem that the base station and the user equipment might haveinconsistent recognitions of content such as the number of pieces ofuplink feedback information or the like in the uplink controlinformation.

To solve the above problem, a DAI (Downlink Assignment Indicator)mechanism is introduced in LTE (Long Term Evolution), where DAI_counteris introduced in downlink scheduling information and DAI_Total isintroduced in uplink scheduling information. A value of DAI_counterindicates the number of pieces of uplink feedback information, whichcorresponds to downlink data and is to be transmitted in the samesubframe as that for the uplink data. A value of DAI_Total is equal tothe value of the last changed DAI_counter. Based on this, the userequipment can determine, from the value of DAI_Total, whether thedownlink scheduling information is missed and the number of pieces ofuplink feedback information that is to be transmitted to the basestation in the same subframe as that for the uplink data.

In LTE, since each of uplink data and uplink control information istransmitted in units of subframes, the uplink control information andthe uplink data either completely overlap or do not overlap at all witheach other in the time domain, that is, there is no case of partialoverlap. Thus, DAI_counter is a count of pieces of uplink feedbackinformation which completely overlaps with uplink data in a subframe inthe time domain.

However, in NR (New Radio), neither uplink data nor uplink controlinformation is transmitted in a fixed unit. There may be a case wherethe uplink data and the uplink control information partially overlapwith each other in the time domain, or a case where two pieces of uplinkfeedback information do not overlap with each other in the time domain,but overlap respectively with two pieces of uplink data in the timedomain. For such cases, according to the mechanism in the related art,the value of DAI_counter cannot be determined and thus the value ofDAI_Total cannot be determined, so that the user equipment cannotdetermine the number of pieces of uplink feedback information that istransmitted to the base station in the same subframe as that for theuplink data.

DETAILED DESCRIPTION

The following will clearly and completely describe the technicalsolutions in the embodiments of the present disclosure with reference tothe accompanying drawings in the embodiments of the present disclosure.Apparently, the described embodiments are only a part of the embodimentsof the present disclosure, but not all of the embodiments. Based on theembodiments in the present disclosure, all other embodiments obtained bya person of ordinary skill in the art without creative efforts shallfall within the protection scope of the present disclosure.

FIG. 1 is a schematic flowchart illustrating a method of indicatinguplink feedback information according to an example of the presentdisclosure. The method of indicating uplink feedback information shownin the example can be applied to a base station. As shown in FIG. 1, themethod of indicating uplink feedback information can include thefollowing steps.

At step S11, time/frequency resources which can be used by userequipment to transmit uplink control information are divided into atleast one time/frequency resource set for the uplink controlinformation.

FIG. 2 is a schematic diagram illustrating a time/frequency resourceaccording to an example of the present disclosure.

In an example, for example, uplink control information, indicated bydownlink scheduling information sent from a base station to the userequipment, has a size of 2 bits, and then the time/frequency resourcesfor transmitting the uplink control information can be 4 types. As shownin FIG. 2, for time slot n, one time slot contains 14 symbols, thetime/frequency resources that the user equipment can use to transmit theuplink control information include first time/frequency resource 1,second time/frequency resource 2, third time/frequency resource 3 andfourth time/frequency resource 4.

In an example, the rules for dividing the set can be pre-configured tothe base station and the user equipment by a protocol, or can be set bythe base station according to requirement. When the base station sideconfigures the division rule with respect to the set according to therequirement, the base station may send the division rule with respect tothe set to the user equipment, or send a division result with respect tothe set to the user equipment, or send both of the division rule andresult with respect to the set to the user equipment.

In an example, the following description is based on the example shownin FIG. 2.

For example, according to a first manner, all resources in time slot nare divided into one set, then set 1 includes first time/frequencyresource 1, second time/frequency resource 2, third time/frequencyresource 3, and fourth time/frequency resources 4.

For example, according to a second manner, all resources in time slot nare divided into two sets. For example, set 1 includes firsttime/frequency resource 1 and second time/frequency resource 2, and set2 includes third time/frequency resource 3 and fourth time/frequencyresource 4.

For example, according to a third manner, all resources in time slot nare divided into three sets. For example, set 1 includes firsttime/frequency resource 1, set 2 includes second time/frequency resource2, and set 3 includes third time/frequency resource 3 and fourthtime/frequency resource 4.

It should be noted that the rules for dividing into the sets are notlimited to the above three manners, and are not limited to the divisionof the above four time/frequency resources, which will not be elaboratedherein.

At step S12, based on the set to which time/frequency resources fortransmitting uplink feedback information corresponding to downlink datafor the user equipment belong, pieces of the uplink feedback informationare counted in a preset manner.

In an example, the uplink feedback information can be included in theuplink control information. The uplink feedback information can beuplink feedback information for HARQ (Hybrid Automatic Repeat reQuest).

In an example, there may be various preset manners, such as a presetorder of cells, a preset order of carrier frequencies, a presetchronological order and so on.

For example, counting according to a preset order of cells, and thepreset order of cells is cell 1, cell 2, and cell 3. The uplink feedbackinformation of cell 1 can be counted first, then the uplink feedbackinformation of cell 2 can be counted, and then the uplink feedbackinformation of cell 3 is counted. The count value corresponding to cell1 to cell 3 is incremented according to the number of the recordeduplink feedback information.

In an example, a time/frequency resource used to transmit the uplinkfeedback information corresponding to the downlink data for the userequipment can be determined according to DCI (Downlink ControlInformation).

For example, taking 7 DCIs as an example, the time/frequency resourceused to transmit the uplink feedback information corresponding todownlink data indicated by DCI 1, DCI 3, and DCI 4 is firsttime/frequency resource 1, the time/frequency resource used to transmitthe uplink feedback information corresponding to downlink data indicatedby DCI 2, and DCI 6 is second time/frequency resource 2, thetime/frequency resource used to transmit the uplink feedback informationcorresponding to downlink data indicated by DCI 5 is thirdtime/frequency resource 3, and the time/frequency resource used totransmit the uplink feedback information corresponding to downlink dataindicated by DCI 7 is fourth time/frequency resource 4.

In this case, based on the three set division manners, the correspondingcount values are as follows.

Based on the first manner, where first time/frequency resource 1, secondtime/frequency resource 2, third time/frequency resource 3, and fourthtime/frequency resource 4 belong to the same set, pieces of uplinkfeedback information indicated by DCI 1 to DCI 7 are countedcontinuously. Since the size of the uplink control information is 2bits, count values are 1, 2, 3, 0, 1, 2, 3.

Based on the second manner, where first time/frequency resource 1 andsecond time/frequency resource 2 belong to set 1, pieces of uplinkfeedback information indicated by DCI 1 to DCI 4 and DCI 6 are countedcontinuously, and count values are 1, 2, 3, 0, 1. Based on the secondmanner, where third time/frequency resource 3 and fourth time/frequencyresource 4 belong to set 2, pieces of uplink feedback informationindicated by DCI 5 and DCI 7 are counted continuously, and count valuesare 1, 2. Further, according to the order of DCI 1 to DCI 7, the countvalues are sorted as 1, 2, 3, 0, 1, 1, 2.

Based on the third manner, where first time/frequency resource 1 belongsto set 1, pieces of uplink feedback information indicated by DCI 1, DCI3, and DCI 4 are counted continuously, and count values are 1, 2, and 3.Based on the third manner, where second time/frequency resource 2belongs to set 2, pieces of uplink feedback information indicated by DCI2 and DCI 6 are counted continuously, and count values are 1, 2. Basedon the third manner, where third time/frequency resource 3 and fourthtime/frequency resource 4 belong to set 3, pieces of uplink feedbackinformation indicated by DCI 5 and DCI 7 are continuously counted, andcount values are 1, 2. Further, according to the order of DCI 1 to DCI7, the count values are sorted as 1, 1, 2, 3, 1, 2, 2.

At step S13, when transmitting downlink scheduling information and/oruplink scheduling information, one or more current count values aretransmitted to the user equipment.

In an example, the current count value refers to a latest count value ofthe continuous counting of the uplink feedback information indicated bythe DCI when the base station transmits the downlink schedulinginformation and/or the uplink scheduling information, and the number ofthe current count value is equal to the number of the sets. For example,based on the first manner, the number of current count value is one, andthe current count value is 3. For example, based on the second manner,the number of current count values is two, and the current count valuesare 1 and 2. For example, based on the third manner, the number ofcurrent count values is three, and the current count values are 3, 2,and 2.

In an example, the user equipment may determine, according topre-configuration, a division rule and/or result with respect to thetime/frequency resource set for the uplink control information, and mayalso receive, from the base station, the division rule and/or resultwith respect to the time/frequency resource set for the uplink controlinformation. As an example, if the user equipment can determine thedivision result with respect to the time/frequency resource set for theuplink control information, the current count value is transmitted tothe user equipment, such that the user equipment can determine,according to the current count value, the number of pieces of uplinkfeedback information to be transmitted by multiplexing thetime/frequency resources for transmitting uplink data. Thus, it can beensured that the number of pieces of uplink feedback information to betransmitted from the user equipment by multiplexing time/frequencyresources for transmitting uplink data is the same as the number ofpieces of downlink data which is transmitted from a base station andcorresponds to the uplink feedback information, thereby ensuring goodcommunication between the user equipment and the base station.

FIG. 3 is a schematic flowchart illustrating another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 3, on the basis of the exampleshown in FIG. 1, the method of indicating uplink feedback informationfurther includes step S14.

At step S14, a division rule and/or result with respect to thetime/frequency resource set for transmitting the uplink controlinformation are notified to the user equipment.

In an example, the division rule and/or result with respect to the setcan be configured by the base station as required. The base station maysend the division rule with respect to the set to the user equipment,may send the division result with respect to the set to the userequipment, or may also send the division rule and result with respect tothe set to the user equipment.

An execute order of step S14 can be configured as required, it can beexecuted prior to step S13, or can be executed simultaneously with stepS13.

FIG. 4 is a schematic flowchart illustrating still another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 4, on the basis of the exampleshown in FIG. 1, dividing the time/frequency resources which can be usedby the user equipment to transmit the uplink control information into atleast one time/frequency resource set for the uplink control informationincludes step S111 and S112.

At step S111, the dividing is performed according to start and/or endpositions of time/frequency resources for the uplink control informationin a time domain.

Alternatively, at step S112, the dividing is preformed according to atime unit to which the time/frequency resources for the uplink controlinformation belong in the time domain.

In an example, there are many ways to perform the dividing.

For example, based on set division according to the start and/or endpositions of the time/frequency resources for the uplink controlinformation in the time domain at step S111, the time/frequencyresources with the same start and/or end positions in the time domainare divided into one set. For example, based on the example shown inFIG. 2, first time/frequency resource 1 and second time/frequencyresource 2 start at the same time, and third time/frequency resource 3and fourth time/frequency resource start at the same time. Then firsttime/frequency resource 1 and second time/frequency resource 2 aredivided into one set, and third time/frequency resource 3 and fourthtime/frequency resource 4 are divided into one set.

For example, based on the set division according to the time unit towhich the time/frequency resources of the uplink control informationbelong in the time domain at S112, the time/frequency resource belongingto the same time unit can be divided into one set. For example, based onthe example shown in FIG. 2, the time unit is a time slot (it should benoted that the time unit can be configured as required), firsttime/frequency resource 1, second time/frequency resource 2, thirdtime/frequency resource 3, and fourth time/frequency resource 4 belongto the same time slot, so first time/frequency resource 1, secondtime/frequency resource 2, third time/frequency resource 3, and fourthtime/frequency resource 4 can be divided into one set.

FIG. 5 is a schematic flowchart illustrating still another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 5, on the basis of the exampleshown in FIG. 1, counting the pieces of the uplink feedback informationin the preset manner includes step S121.

At step S121, the pieces of the uplink feedback information inrespective ones of the sets are counted in the preset manner.

In one example, the pieces of the uplink feedback information combinedin respective ones of the sets can be counted separately. For example,based on the above second manner, where first time/frequency resource 1and second time/frequency resource 2 belong to set 1, pieces of theuplink feedback information indicated by DCI 1 to DCI 4 and DCI 6 arecounted continuously, and the count values are 1, 2, 3, 0, 1. Based onthe above second manner, where third time/frequency resource 3 andfourth time/frequency resource 4 belong to set 2, pieces of the uplinkfeedback information indicated by DCI 5 and DCI 7 are countedcontinuously, and the count values are 1, 2. Further, according to theorder of DCI 1 to DCI 7, the count values are sorted as 1, 2, 3, 0, 1,1, 2.

In view of this, it can ensure that one or more current count valuereceived by the user equipment correspond to a set to which thetime/frequency resources belong, such that the user equipment quicklydetermines, according to the current count value, a number of pieces ofdownlink scheduling information included in the set corresponding to thecurrent count value. For example, based on the example shown in FIG. 1,the downlink scheduling information is DCI, and the current count valuesreceived based on the above manner are 1 and 2, so it can be determinedthat 5 DCIs corresponding to set 1 and 2 DCIs corresponding set 2 needto be received.

FIG. 6 is a schematic flowchart of still another method of indicatinguplink feedback information according to an example of the presentdisclosure. As shown in FIG. 6, on the basis of the example shown inFIG. 1, transmitting the current count value to the user equipmentincludes step S131 and/or S132.

At step S131, a first set of the sets to which the time/frequencyresources for transmitting the uplink feedback information correspondingto the downlink scheduling information belong is determined, and acurrent count value corresponding to the first set is selected fortransmission to the user equipment.

In an example, after the downlink scheduling information is determined,the uplink feedback information corresponding to the downlink schedulinginformation may be determined, the first set of the divided sets towhich the time/frequency resources for transmitting the uplink feedbackinformation belong can be further determined, where the first set may beone or more sets. And further, the current count value corresponding tothe first set can be transmitted to the user equipment. As for a setother than the first set, since the time/frequency resources fortransmitting the uplink feedback information do not belong to such set,such set does not involve multiplexing the time/frequency resources fortransmitting the uplink data, and there is no need to notify the userequipment such set, therefore it is beneficial to reducing an amount ofdata to be transmitted.

Additionally, or alternatively, at step S132, according to thetime/frequency resources for transmitting uplink data corresponding tothe uplink scheduling information, and time/frequency resources fortransmitting the uplink control information included in respective onesof the sets, one or more corresponding ones of the current count valuesare selected for transmission to the user equipment.

In an example, the uplink scheduling information is uplink schedulinginformation currently transmitted to the user equipment from the basestation, and one or more current count values corresponding to a setincluding the uplink scheduling information can be selected to betransmitted to the user equipment, instead of transmitting the currentcount values corresponding to all of the sets to the user equipment.

FIG. 7 is a schematic flowchart illustrating still another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 7, on the basis of the exampleshown in FIG. 6, when a plurality of ones of the current count valuesare selected, the method further includes step S15.

At step S15, a number of the selected current count values aretransmitted to the user equipment.

In an example, the number of the selected current count values can betransmitted to the user equipment, so that the user equipment candetermine whether a count value has been missed according to the numberand the received count values. When it is determined that a count valuehas been missed, the user equipment can send a request to the basestation for requesting the base station to retransmit the current countvalue.

FIG. 8 is a schematic flowchart illustrating still another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 8, on the basis of the exampleshown in FIG. 6, selecting the one or more corresponding ones of thecurrent count values for transmission to the user equipment includesstep S1321 or S1322.

At step S1321, when the time/frequency resources for transmitting theuplink data overlap, in a time domain, with time/frequency resources fortransmitting any uplink control information included in a second set ofthe sets, a current count value corresponding to the second set isselected for transmission to the user equipment. The second set is oneor more sets of the divided set, and a set of the second set can be thesame as or different from a set of the first set.

In an example, in response to that the time/frequency resources fortransmitting the uplink data corresponding to the uplink schedulinginformation are determined, the time/frequency resources fortransmitting the uplink control information included in the divideddifferent sets can be determined. When the time/frequency resources fortransmitting the uplink control information included in the second setof the divided sets overlap with the time/frequency resources fortransmitting the uplink data in the time domain, it is necessary tomultiplex the time/frequency resources for transmitting the uplink data.When a set including time/frequency resources for transmitting theuplink control information does not overlap with the time/frequencyresources for transmitting the uplink data, it is not necessary tomultiplex the time/frequency resources for transmitting the uplink data.Therefore, it is possible to only transmit, to the user equipment, thecurrent count value corresponding to the second set to which theoverlapping time/frequency resources for the uplink control informationbelong, which is beneficial to reducing the amount of data to betransmitted.

Alternatively, at step S1322, the current count values respectivelycorresponding to the sets are transmitted to the user equipment.

In an example, different from the example associated with step S1321,the count value corresponding to each set can be directly transmitted tothe user equipment, so as to reduce the resources consumed by the basestation for analysis.

FIG. 9 is a schematic flowchart illustrating still another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 9, on the basis of the exampleshown in FIG. 6, when a plurality of ones of the current count valuesare selected, the method of indicating uplink feedback informationfurther includes step S16.

At step S16, an order of the count values is determined.

In an example, when there are a plurality of the current count values,the order of the plurality of the current count values may betransmitted to the user equipment, such that the user equipment candetermine the order of the plurality of received current count values.For example, based on the third manner in the example shown in FIG. 1,three current count values, 3, 2 and 2, can be received.

Since the user equipment can determine the division rule and/or resultwith respect to the set, when the user equipment cannot determine theorder of the three current count values, current count value 2 might beused as the first count value, and then the user equipment might decidethat there are two pieces of uplink feedback information associated withthe time/frequency resources corresponding to set 1. In fact, the basestation requires that there are three pieces of uplink feedbackinformation associated with the time/frequency resources correspondingto set 1 in the user equipment. Therefore, a problem in communicationbetween the user equipment and the base station is caused. Bytransmitting the order of the current count values to the userequipment, it can be ensured that the user equipment can accuratelydetermine the number of pieces of uplink feedback information associatedwith the time/frequency resources in a set corresponding to each of thecurrent count values, thereby ensuring good communication between theuser equipment and the base station.

The timing to perform step S16 can be set as required, step S16 can beperformed prior to step S13, or can be performed simultaneously withstep S13.

FIG. 10 is a schematic flowchart illustrating still another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 10, on the basis of the exampleshown in FIG. 9, determining the order of the count values includes stepS161.

At step S161, the order of the count values is determined according to aconfiguration order of the sets corresponding to the current countvalues in the dividing.

In an example, the order of the current count values can be the same asthe configuration order when the sets are divided by the base station.For example, based on the third manner shown in FIG. 1, if theconfiguration order of sets is set 1, set 2, and set 3, then the orderof the current count values is 3, 2, 2; if the configuration order ofsets is set 2, set 3, set 1, then the order of the current count valuesis 2, 2, 3.

FIG. 11 is a schematic flowchart illustrating still another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 11, on the basis of the exampleshown in FIG. 9, determining the order of the count values includes stepS162.

At step S162, the order of the count values is determined according torespective positions in a time domain and/or frequency domain of thetime/frequency resources for transmitting the uplink control informationin the sets.

In an example, the order of the current count values can be the same asan order of the positions of the time/frequency resources used fortransmitting the uplink control information in the sets in the timedomain and/or in the frequency domain. For example, taking the positionsof time/frequency resources used for transmitting the uplink controlinformation in the sets in the time domain as an example, based on thesecond manner shown in FIG. 1, where set 1 includes first time/frequencyresource 1 and second time/frequency resource 2, the positions of whichin the time domain are more advanced compared to those of thirdtime/frequency resource 3 and fourth time/frequency resource 4 includedin set 2. Therefore, the determined order of the count values can be thecurrent count value corresponding to set 1, and then the current countvalue corresponding to set 2.

It should be noted that the manner of determining the order of the countvalues is not limited to the above manners, which will not be elaboratedherein.

FIG. 12 is a schematic flowchart illustrating still another method ofindicating uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 12, on the basis of the exampleshown in FIG. 9, the method of indicating uplink feedback informationfurther includes step S17.

At step S17, the order is notified to the user equipment.

In an example, the order of the count values can be notified by the basestation to the user equipment.

In an example, the order of the count values can be pre-configured tothe user equipment, thus the notification from the base station is notnecessary.

FIG. 13 is a schematic flowchart illustrating a method of transmittinguplink feedback information according to an example of the presentdisclosure. The method of transmitting uplink feedback information shownin the example can be applicable to user equipment. As shown in FIG. 13,the method of transmitting uplink feedback information may include thefollowing steps.

At step S31, according to a same division rule and/or result as that,used by a base station, with respect to a time/frequency resource setfor transmitting uplink control information, time/frequency resources,which can be used by the user equipment to transmit the uplink controlinformation, are divided into at least one time/frequency resource setfor the uplink control information.

At step S32, when receiving downlink scheduling information and/oruplink scheduling information, one or more current count values from thebase station are received.

At step S33, according to the current count value, time/frequencyresources indicated by the downlink scheduling information fortransmitting uplink feedback information, the division rule and/orresult with respect to the set, and time/frequency resources indicatedby the uplink scheduling information for transmitting uplink data,uplink feedback information to be transmitted by multiplexing thetime/frequency resources for transmitting the uplink data is determined.

At step S34, the uplink feedback information is transmitted to the basestation by multiplexing the time/frequency resources for transmittingthe uplink data.

In an example, the user equipment can divide time/frequency resources,which can be used by the user equipment to transmit the uplink controlinformation, into a set, according to the same division rule and/orresult as that, by the base station, for the time/frequency resourcesused for transmitting the uplink control information. Based on this, thetime/frequency resources for transmitting the uplink control informationincluded in a set divided by the base station correspond to thetime/frequency resources for transmitting the uplink control informationincluded in a set divided by the user equipment. For example, a firstset divided by the base station includes the number, time domainpositions, and frequency domain positions of the time/frequencyresources for transmitting the uplink control information, which arerespectively the same as the number, time domain positions, andfrequency domain positions of the time/frequency resources fortransmitting the uplink control information which are included in afirst set divided by the user equipment.

In an example, the user equipment can further receive the current countvalue from the base station, and according to the current count value,the user equipment can determine the number of pieces of uplink feedbackinformation to be transmitted by multiplexing the time/frequencyresources for transmitting the uplink data.

According to the time/frequency resources indicated by the downlinkscheduling information for transmitting the uplink feedback information,the time/frequency resources for transmitting the uplink feedbackinformation can be determined. According to the time/frequency resourcesindicated by the uplink scheduling information for transmitting theuplink data, the time/frequency resources for transmitting the uplinkdata can be determined. Therefore, it can be determined whether there isan overlap between the time/frequency resources for transmitting theuplink feedback information and the time/frequency resources fortransmitting the uplink data, and determined a set corresponding tooverlapped time/frequency resources for transmitting the uplink feedbackinformation.

The uplink feedback information, corresponding to the time/frequencyresources for transmitting the uplink feedback information which overlapwith the time/frequency resources for transmitting the uplink data, maybe determined as the uplink feedback information to be transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata. Uplink feedback information, corresponding to each time/frequencyresource for transmitting the uplink data in a set associated with theoverlapped time/frequency resources for transmitting the uplink feedbackinformation, may also be determined as the uplink feedback informationto be transmitted by multiplexing the time/frequency resources fortransmitting the uplink data.

Based on the content determined above, the user equipment can transmitthe uplink feedback information, which is to be transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata, on the time/frequency resources for transmitting the uplink datain the set divided by the base station, and the number of pieces ofuplink feedback information transmitted is the same as the number ofpieces of uplink feedback information required by the base station,thereby ensuring good communication between the user equipment and thebase station.

FIG. 14 is a schematic diagram illustrating transmitting uplink feedbackinformation according to an example of the present disclosure.

As shown in FIG. 14, for example, corresponding to the first manner inthe example shown in FIG. 1, there is one divided set, and the currentcount value transmitted is 3. Then it can be determined that the numberof pieces of uplink feedback information to be transmitted to the basestation is 7. Since time/frequency resources for transmitting the uplinkfeedback information included in set 1 (that is, 1, 2, 3, and 4 in FIG.14) overlap with time/frequency resource 5 for transmitting the uplinkdata (that is, there is an overlap between 1, 2 and 5), each piece ofuplink feedback information corresponding to a time/frequency resourcefor transmitting the uplink feedback information in set 1 can bedetermined as the uplink feedback information to be transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata. Therefore, uplink feedback information 6 (the number thereof is 7)to be transmitted by multiplexing the time/frequency resource fortransmitting the uplink data can be transmitted to the based station ontime/frequency resource 5 for transmitting the uplink data. In this way,no uplink feedback information is transmitted on first time/frequencyresource 1, second time/frequency resource 2, third time/frequencyresource 3, and fourth time/frequency resource 4.

Since one set is obtained by dividing according to the first manner, andthe one set corresponds to only one current count value. It is notnecessary to determine the order of the current count values. It is onlynecessary to sort the pieces of uplink feedback information 6 accordingto an order of DCIs. That is, in the time domain and/or frequency domainof time/frequency resource 5 for transmitting the uplink data, thepieces of uplink feedback information are sorted according to the orderof DCI 1 to DCI 7.

When multiple sets are obtained by dividing in other manners, whichcorrespond to multiple current count values, the user equipment can alsoreceive the number of current count values and the order of the currentcount values which are from the base station. For example, FIG. 14corresponds to the third manner in the example shown in FIG. 1, thereare 3 divided sets, and the corresponding current count values are 3, 2,and 2. By determining an order of the current count values, the userequipment can determine that the current count values are arranged inthe order of 3, 2, and 2, and then, according to the division resultwith respect to the set, the user equipment can determine that thepieces of uplink feedback information in set 1 correspond to DCI 1, DCI3, and DCI 4, the pieces of uplink feedback information in set 2correspond to DCI 2 and DCI 6, the pieces of uplink feedback informationin set 3 correspond to DCI 5 and DCI 7. Thus, the pieces of uplinkfeedback information can be sorted in the time domain and/or frequencydomain of time/frequency resource 5 for transmitting the uplink data,that is, the pieces of the uplink feedback information can be sortedcorresponding to the order of DCI 1, DCI 3, DCI 4, DCI 2, DCI 6, DCI 5,and DCI 7 respectively.

FIG. 15 is another schematic diagram illustrating transmitting uplinkfeedback information according to an example of the present disclosure.

As shown in FIG. 15, for example, corresponding to the second manner inthe example shown in FIG. 1, there are 2 divided sets, and thetransmitted current count values are 1 and 2. Then, it can be determinedthat the number of pieces of uplink feedback information to betransmitted to the base station is 7. Since time/frequency resources fortransmitting uplink feedback information included in set 1 (that is, 1and 2 in FIG. 15) overlap with time/frequency resource 5 fortransmitting the uplink data, and time/frequency resources fortransmitting uplink feedback information included in set 2 (that is, 3and 4 in FIG. 15) do not overlap with time/frequency resource 5 fortransmitting the uplink data, uplink feedback information, correspondingto the time/frequency resources for transmitting the uplink feedbackinformation included in set 1 (that is, 1 and 2 in FIG. 15) whichoverlap with the time/frequency resource for transmitting the uplinkdata, can be determined as the uplink feedback information to betransmitted by multiplexing the time/frequency resources fortransmitting the uplink data. Therefore, uplink feedback information 6(the number thereof is 5) to be transmitted by multiplexing thetime/frequency resource for transmitting the uplink data can betransmitted to the based station on time/frequency resource 5 fortransmitting the uplink data. Thus, no uplink feedback information istransmitted on first time/frequency resource 1 and second time/frequencyresource 2.

For third time/frequency resource 3 and fourth time/frequency resource 4in set 2, there is no overlap in the time domain with time/frequencyresource 5 for transmitting uplink data, so there is no need to transmitthe uplink feedback information corresponding to third time/frequencyresource 3 and fourth time/frequency resource 4 by multiplexingtime/frequency resource 5 for transmitting the uplink data. Rather, theuplink feedback information corresponding to third time/frequencyresource 3 and fourth time/frequency resource 4 can be transmitted in atime division multiplexed manner.

FIG. 16 is still another schematic diagram illustrating transmittinguplink feedback information according to an example of the presentdisclosure.

As shown in FIG. 16, for example, corresponding to the first manner inthe example shown in FIG. 1, there is one divided set, and the currentcount value transmitted is 3. Then, it can be determined that the numberof pieces of uplink feedback information to be transmitted to the basestation is 7. Since time/frequency resources for transmitting uplinkfeedback information included in set 1 overlap with time/frequencyresource 5 for transmitting uplink data (that is, 2, 3 and 4 in FIG.16), each piece of uplink feedback information corresponding to atime/frequency resource for transmitting the uplink feedback informationin set 1 can be determined as the uplink feedback information to betransmitted by multiplexing the time/frequency resources fortransmitting uplink data. Therefore, uplink feedback information 6 (thenumber thereof is 7) to be transmitted by multiplexing thetime/frequency resource for transmitting the uplink data can betransmitted to the based station on time/frequency resource 5 fortransmitting the uplink data. Thus, no uplink feedback information isrequired to be transmitted on first time/frequency resource 1, secondtime/frequency resource 2, third time/frequency resource 3, and fourthtime/frequency resource 4.

FIG. 17 is still another schematic diagram illustrating transmittinguplink feedback information according to an example of the presentdisclosure.

As shown in FIG. 17, for example, corresponding to the third manner inthe example shown in FIG. 1, there are 3 divided sets, and the currentcount values transmitted are 3, 2 and 2. Then, it can be determined thatthe number of pieces of uplink feedback information to be transmitted tothe base station is 7. Since time/frequency resource for transmittinguplink feedback information included in set 1 (that is, 1 in FIG. 17)does not overlap with time/frequency resource 5 for transmitting theuplink data, time/frequency resource for transmitting uplink feedbackinformation included in set 2 (that is, 2 in FIG. 17) overlaps withtime/frequency resource 5 for transmitting the uplink data, andtime/frequency resources for transmitting uplink feedback informationincluded in set 3 (that is, 3 and 4 in FIG. 17) overlap withtime/frequency resource 5 for transmitting the uplink data, uplinkfeedback information, corresponding to the time/frequency resources fortransmitting uplink feedback information include in set 2 and set 3(that is, 2, 3 and 4 in FIG. 17) which overlap with time/frequencyresource 5 for transmitting the uplink data, can be determined as theuplink feedback information to be transmitted by multiplexing thetime/frequency resources for transmitting uplink data. Therefore, uplinkfeedback information 6 (the number thereof is 4) to be transmitted bymultiplexing the time/frequency resource for transmitting the uplinkdata can be transmitted to the based station on time/frequency resource5 for transmitting the uplink data. Thus, no uplink feedback informationto be transmitted on second time/frequency resource 2, thirdtime/frequency resource 3 and fourth time/frequency resource 4.

For first time/frequency resource 3 in set 1, there is no overlap in thetime domain with time/frequency resource 5 for transmitting uplink data,so there is no need to transmit the uplink feedback informationcorresponding to first time/frequency resource 1 by multiplexingtime/frequency resource 5 for transmitting the uplink data.

Optionally, the division rule and/or result are pre-configured and/orreceived from a base station when receiving the downlink schedulinginformation and/or the uplink scheduling information.

FIG. 18 is a schematic flowchart illustrating another method oftransmitting uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 18, on the basis of the exampleshown in FIG. 13, if a number of the count values is more than one, themethod of transmitting uplink feedback information further includessteps S35 and S36.

At step S35, a number of the count values from the base station isreceived.

At step S36, it is determined whether a count value is missed accordingto the number and a number of received count values.

In an example, the user equipment can count the number of the currentcount values received and compare it with the number from the basestation. If the number of the current count values is less than(generally there is no case of being greater than) the number from thebase station, it can be determined that one or more current count valuesare missed. In this way, a request can be sent to the base station forrequesting the base station to resend the current count values.

In an example, after requesting the base station to resend the currentcount values, if the user equipment receives the current count valuesresent by the base station, the user equipment can determine the uplinkfeedback information to be transmitted by multiplexing thetime/frequency resources for transmitting the uplink data, according tothe resent current count values, the time/frequency resources indicatedby the downlink scheduling information for transmitting the uplinkfeedback information, the division rule and/or result with respect tothe set, and the time/frequency resources indicated by the uplinkscheduling information for transmitting the uplink data.

In an example, if the number of the count values is more than one, themethod further includes the following step.

An order of the count values from the base station is received.

According to the current count values, the time/frequency resourcesindicated by the downlink scheduling information for transmitting theuplink feedback information, the division rule and/or result withrespect to the set, and the time/frequency resources indicated by theuplink scheduling information for transmitting the uplink data,determining the uplink feedback information to be transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata includes the followings.

The uplink feedback information to be transmitted by multiplexing thetime/frequency resources for transmitting the uplink data is determinedaccording to the time/frequency resources indicated by the downlinkscheduling information for transmitting the uplink feedback information,the division rule and/or result with respect to the set, thetime/frequency resources indicated by the uplink scheduling informationfor transmitting the uplink data, and the order.

FIG. 19 is a schematic flowchart illustrating determining uplinkfeedback information to be transmitted by multiplexing time/frequencyresources for transmitting uplink data according to an example of thepresent disclosure. As shown in FIG. 19, on the basis of the exampleshown in FIG. 13, determining the uplink feedback information to betransmitted by multiplexing the time/frequency resources fortransmitting the uplink data includes steps S331-S333.

At step S331, the time/frequency resources indicated by the uplinkscheduling information for transmitting the uplink data are determined.

At step S332, a time/frequency resource set corresponding to a currentcount value greater than zero is determined, the time/frequency resourceset is received when the downlink scheduling information and/or theuplink scheduling information is received.

At step S333, among the uplink feedback information indicated by thedownlink scheduling information, uplink feedback information, of whichtime/frequency resources for transmission belonging to a time/frequencyresource set corresponding to the current count value greater than zeroare to be used, is determined as the uplink feedback information bymultiplexing the time/frequency resources for the uplink data.

In an example, if the current count value is equal to 0, it is necessaryto determine whether the current count value is really equal to 0according to the actual situation. For example, it can be detectedwhether receives the downlink scheduling information indicating uplinkfeedback information. If the downlink scheduling information isreceived, it can be determined that the current count value is not 0,but an integer multiple of 4. If the downlink scheduling information isnot received, it can be determined that the count value is indeed 0.

In an example, for a set corresponding to a current count value greaterthan 0, it can be determined that the base station has indicated thatuplink feedback information corresponding to a resource used for theuplink feedback information in the set multiplexes the time/frequencyresources for transmitting the uplink data. For a set corresponding tothe current count value which is equal to 0, it can be determined thatthe base station has not indicated that the uplink feedback informationcorresponding to a resource used for the uplink feedback information inthe set multiplexes the time/frequency resources for transmitting theuplink data. Therefore, only the uplink feedback information, for thetransmission of which time/frequency resources belonging to thetime/frequency resource set corresponding to the current count valuegreater than zero are to be used, is determined as the uplink feedbackinformation to be transmitted by multiplexing the time/frequencyresources for the uplink data, and other uplink feedback information canbe transmitted to the base station in other ways.

FIG. 20 is a schematic flowchart illustrating still another method oftransmitting uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 20, on the basis of the exampleshown in FIG. 13, if the time/frequency resources for transmittinguplink control information are in different time units, beforetransmitting the uplink feedback information to the base station bymultiplexing the time/frequency resources for transmitting the uplinkdata, the method of transmitting uplink feedback information includesstep S37.

At step S37, uplink feedback information to be transmitted bymultiplexing time/frequency resources for transmitting uplink data ineach of the different time units is determined.

Transmitting the uplink feedback information to the base station bymultiplexing time/frequency resources for transmitting the uplink dataincludes step S334.

At step S334, for each of the different time units, according to theuplink feedback information determined in each time unit, the uplinkfeedback information is transmitted to the base station by multiplexingtime/frequency resources for transmitting uplink data in correspondingtime unit. The corresponding time unit refers to a time unitcorresponding to the determined uplink feedback information.

In an example, if the time/frequency resources for transmitting uplinkcontrol information are in different time units, it can be determinedthat, in each time unit, the uplink feedback information is transmittedby multiplexing the time/frequency resources used for transmittinguplink data. Furthermore, in each time unit, the uplink feedbackinformation can be transmitted by multiplexing the time/frequencyresources used for transmitting uplink data according to themultiplexing situation of time/frequency resources used for transmittingthe uplink feedback information and the uplink data in the respectivetime unit. For example, for a first time unit in the different timeunits, the uplink feedback information can be transmitted bymultiplexing the time/frequency resources used for transmitting uplinkdata according to the multiplexing situation of time/frequency resourcesused for transmitting the uplink feedback information and the uplinkdata in the first time unit. For a second time unit in the differenttime units, the uplink feedback information can be transmitted bymultiplexing the time/frequency resources used for transmitting uplinkdata according to the multiplexing situation of time/frequency resourcesused for transmitting the uplink feedback information and the uplinkdata in the second time unit.

FIG. 21 is a schematic flowchart illustrating still another method oftransmitting uplink feedback information according to an example of thepresent disclosure. As shown in FIG. 21, on the basis of the exampleshown in FIG. 13, if the time/frequency resources for transmittinguplink control information are in different time units, beforetransmitting the uplink feedback information to the base station bymultiplexing the time/frequency resources for transmitting the uplinkdata, the method of transmitting uplink feedback information includesstep S38.

At step S38, uplink feedback information to be transmitted bymultiplexing time/frequency resources for transmitting uplink data ineach of the different time units is determined.

Transmitting the uplink feedback information to the base station bymultiplexing time/frequency resources for transmitting the uplink dataincludes step S335.

At step S335, in each of the different time units, the determined uplinkfeedback information to be transmitted by multiplexing thetime/frequency resources for transmitting the uplink data is combined inrespective ones of the different time units, and the uplink feedbackinformation is transmitted to the base station by multiplexing thetime/frequency resources for transmitting the uplink data.

In an example, if the time/frequency resources for transmitting uplinkcontrol information are in different time units, it can be determinedthat, in each time unit, the uplink feedback information to betransmitted by multiplexing the time/frequency resources used fortransmitting uplink data. Then, uplink feedback information to bemultiplexed with time/frequency resources used for transmitting uplinkdata determined in each time unit is combined. Then, in each time unit,the combined uplink feedback information is transmitted to the basestation by multiplexing the time/frequency resources used fortransmitting uplink data. For example, for a first time unit indifferent time units, according to the multiplexing situation of thetime/frequency resources used for transmitting the uplink feedbackinformation and the uplink data in the first time unit and a second timeunit, the uplink feedback information is transmitted by multiplexing thetime/frequency resources used for transmitting uplink data. For thesecond time unit in different time units, according to the multiplexingsituation of the time/frequency resources used for transmitting theuplink feedback information and the uplink data in the first time unitand the second time unit, the uplink feedback information is transmittedby multiplexing the time/frequency resources used for transmittinguplink data.

FIG. 22 is still another schematic diagram illustrating transmittinguplink feedback information according to an example of the presentdisclosure.

In an example, as shown in FIG. 22, for example, there are still 7 DCIsfrom DCI 1 to DCI 7. Pieces of uplink feedback information indicated byDCI 1, DCI 3, and DCI 4 correspond to first time/frequency resource 1 intime slot n, pieces of uplink feedback information indicated by DCI 2and DCI 6 correspond to second time/frequency resource 2 in time slotn+1, a piece of uplink feedback information indicated by DCI 3corresponds to third time/frequency resource 3 in time slot n, and apiece of uplink feedback information indicated by DCI 4 corresponds tofourth time/frequency resource 4 in time slot n+1. The division rulewith respect to the set is: set 1 includes first time/frequency resource1, set 2 includes second time/frequency resource 2, and set 3 includesthird time/frequency resource 3 and fourth time/frequency resource 4.

In determining the uplink feedback information to be transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata in each of different time units, it can be obtained that, in timeslot n, first time/frequency resource 1 overlaps with time/frequencyresources for transmitting the uplink data, so that the pieces of uplinkfeedback information associated with DCI 1, DCI 3, and DCI 4corresponding to first time/frequency resource 1 require to betransmitted by multiplexing the time/frequency resources fortransmitting the uplink data. And it can be obtained that, in time slotn+1, second time/frequency resource 2 overlaps with time/frequencyresources for transmitting the uplink data, so that the pieces of uplinkfeedback information associated with DCI 2 and DCI 6 corresponding tosecond time/frequency resource 2 require to be transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata.

Based on the example shown in FIG. 22, in combination with the exampledescribed at steps S37 and S334, in each of different time units,according to the uplink feedback information determined in each timeunit, the uplink feedback information is transmitted to the base stationin the corresponding time unit by multiplexing the time/frequencyresources for transmitting the uplink data. That is, in time slot n,only the uplink feedback information which requires to be multiplexedwith time/frequency resources used for transmitting uplink data in timeslot n, is transmitted by multiplexing the time/frequency resources usedfor transmitting the uplink data in time slot n. In time slot n+1, onlythe uplink feedback information which requires to be multiplexed withtime/frequency resources used for transmitting uplink data in time slotn+1, is transmitted by multiplexing the time/frequency resources usedfor transmitting the uplink data in time slot n+1.

In view of this, it can be obtained that in time slot n, the pieces ofthe uplink feedback information associated with DCI 1, DCI 3, and DCI 4corresponding to first time/frequency resource 1 are transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata; in time slot n+1, the pieces of the uplink feedback informationassociated with DCI 2 and DCI 6 corresponding to second time/frequencyresource 2 are transmitted by multiplexing the time/frequency resourcesfor transmitting the uplink data.

Based on the example shown in FIG. 22 and in combination with theexample described at steps S38 and S335, in each of different timeunits, the uplink feedback information to be multiplexed withtime/frequency resources for transmitting the uplink data as determinedin each time unit is combined, and the uplink feedback information istransmitted to the base station by multiplexing the time/frequencyresources for transmitting uplink data. That is, in time slot n, both ofthe uplink feedback information to be multiplexed with time/frequencyresources for transmitting uplink data in time slot n, and the uplinkfeedback information to be multiplexed with time/frequency resources fortransmitting uplink data in time slot n+1, are transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata in time slot n.

Correspondingly, in time slot n+1, both of the uplink feedbackinformation to be multiplexed with the time/frequency resources fortransmitting the uplink data in time slot n, and the uplink feedbackinformation to be multiplexed with the time/frequency resources fortransmitting the uplink data in time slot n+1, are transmitted bymultiplexing the time/frequency resources for transmitting the uplinkdata in time slot n+1.
